1.Description
The DRV8837 module is capable of delivering 1.8A of output current. It operates from a motor supply voltage between 0 and 11V and a device supply voltage in the range of 1.8V to 7V. The DRV8837 module has two PWM (IN/IN) input interfaces; The DRV8837 has a PH/EN input interface that is compatible with industry standard periods and also provides internal shutdown for overcurrent protection, short circuit protection, undervoltage lockout and overtemperature protection.
2. Parameters:
1>.2-way H-bridge motor driver drives 2 DC motors ((MOSFET)
2>.on-resistance: high side + low side (HS + LS) 280mohm)
3>.2 way 1.8A maximum drive current
4>.Independent motor and logic power supply pins:
4.1>.Motor VM: 0 to 11V
4.2>.Logic VC: 1.8 to 7V
5>.Pulse Width Modulation (PWM) or PH/EN interface
6>.DRV8837: Pulse Width Modulation (PWM), IN1/IN2/IN4/IN5
7>.nSLEEP pin Low-power sleep mode with 120nA maximum sleep current
3.Protection characteristics
1>.VCC undervoltage lockout (UVLO)
2>.Overcurrent Protection (OCP)
3>.Thermal shutdown (TSD)
4. Pin introduction:
1>.I1/I2/I3/I4- These 4 are input control ports
2>.O1/O2/O3/O4- These 4 are output DC motors
3>.VC voltage full name VCC is logic voltage input 1.8-7V
4>.VM is motor drive Voltage 0-11V
5>.GD is GND
6>.EP is nSLEEP sleep pin, the short contact VC-VM behind it can short the solder joint when the power supply voltage is small and 7V, it can be powered by one power supply, if it is higher than 7V Please do not short-circuit, the sleep mode is prohibited after the short-circuit of the EP-GD short-circuit solder joint.
